KSP Dually Wheel Spacers 8x170 8x180 8x165.1 12mm - Forged 8 Lug Set

Our review of the KSP Dually Wheel Spacers finds them aimed squarely at owners of heavy-duty trucks who need a modest, reliable wheel offset without major modification. These 1/2' (12mm) forged spacers widen track width to improve clearance for larger tires, correct brake caliper interference and deliver a slightly more aggressive stance. Built from CNC machined 6061-T6 aluminum with a silver anodized finish and supplied in a set of four with thread locker included, the spacers focus on fitment accuracy and corrosion resistance rather than dramatic wheel protrusion.

Key Features

• Multi bolt pattern: The 8-lug design fits 8x165.1mm (8x6.5'), 8x170mm and 8x180mm bolt patterns, offering broad compatibility across many heavy-duty trucks.
• Durable construction: CNC machined from 6061-T6 aluminum billet for strength and precise fit that reduces vibration risk compared with lower quality cast spacers.
• Half-inch thickness: The 12mm thickness provides enough offset to help with larger tire clearance and caliper interference without excessive wheel setback.
• Complete kit: Supplied as a set of four with thread locker included so installation uses correct fasteners and helps maintain clamp integrity.
• Corrosion resistance: Silver anodized surface treatment increases resistance to corrosion for longevity in road environments.
• Large hub bore: A 127mm hub bore and 210mm outside diameter keep the spacer centered and compatible with common dually hubs.

Who It's For

This spacer set is best for owners of 3/4 and 1-ton trucks such as Ford F-250/F-350, Ram 2500/3500 and GM 2500/3500 models who need a modest 1/2' increase in wheel offset to clear larger tires or brake components while maintaining factory-style fitment. It suits drivers who want a subtle stance improvement and improved cornering stability without permanent hub modifications.

Those who need a larger offset, custom wheel backspacing beyond 12mm, or who run unusual aftermarket hubs should look elsewhere. Also, anyone unsure about year/make/model compatibility should verify fit before purchase, as correct matching is required for safe operation.

Pros & Cons

Pros

• Strong, CNC machined 6061-T6 aluminum construction reduces vibration and provides precise fit.
• Broad compatibility across 8-lug heavy-duty trucks thanks to multiple bolt pattern support.
• Includes thread locker and comes as a 4-piece set for a complete installation.
• Silver anodized finish improves corrosion resistance for longer life.

Cons

• At 12mm thickness the offset is modest and may not solve clearance on heavily modified or extreme lift builds.
• Vehicle year/make/model compatibility must be checked carefully before purchase to ensure fit.
